Hi!
Could anyone tell me whether the *sequence* of my calls to timer are allowable
in TinyOS1? For some reason this code stalls while sending to the radio, i.e.
sendone never gets called.
This program gets info from the ADC and sends it to the radio. I want to use
multiple one_shoot timers so I can eventually manipulate the timings between
each call.
Thank you in advance
